I understand that you are getting divergence in temperature and UDS-0. One option is to try with lower URFs but energy, it may take long time to converge. So you switch off the secondary gradients for energy equation by using following TUI command.
(rpsetvar 'temperature/secondary-gradient? #f)
Secondly we can try reducing the explicit URFs of energy by using the following commands.
(rpsetvar 'explicit-relaxation? #t)
(rpsetvar 'temperature/explicit-relax 0.2)
For UDS, you can reduce the under relaxation factor and try running the case. Hope this will help you to avoid the divergence in temperature and UDS.
Thanks & Regards,
